Not enough for smooth tracks (same to you 46u), seriously, take the plunge, try 10-10-2, this is what I used to run on my hyper 7 (which also had an 8 gear spider), it makes it handle much more like a road car, more traction out of the corners. Makes the buggies want to drive more 'on traction' than swinging them round corners. depends entirely on your driving style, but this suited me nicely, as I came from on-road cars, I can't help trying to drive my buggy like an on road car.
